Abstract

Impulsive Noise is one of the degrading factors in digital image quality. In this paper, an innovative and hybrid method for noise reduction is proposed. The proposed algorithm has two stages: detection of the noise and removing of it in the frequency domain. Another innovation of the paper is introducing of a measure of quality assessment of the degraded image. The results show the improving of the quality in comparison with the state of the art related works is achieved and this method outperforms them about 2dB in PSNR measure.
